. BREATHER-PIPE arracnmnnr.

Application filed au ust 2,1927. Serial ne zloan.

This invention relates to an improved device which may be conveniently defined as an attachment for a breather pipe, the same having more particular reference to a device which is adapted to replace the usual breather pipe cap in order to permit an air hose to be connected therewith with a view toward utilizing air pressure for assisting in draining the oil from the crank case.

Briefly, the invention comprises a cap'to.

fit onto the pipe, this cap being provided with screened openings and these being controlled by a. rotary valve. In addition, it includes a. short pipe connection for permitting the hose to be connected thereto, together with resilient means for maintaining the valve in adjusted position.

My principal aim is to provide an exceptionally simple and inexpensive device for the purpose specified, the same being of such construction that it will serve under ordiconstructed in accordance with the present invention showing the approximate manner in which the same 18 used.

Figure 2 is a top plan view of Figure 1' wherein the valve is shown as open.

Figure 3 is also a top plan view with the valve closed.

, Referring to the drawings in detail it will be seen that the reference character A designates the usual breather pipe, while the refj invention has been shown and described, it

erence character 1 designates generally the entire attachment As before stated, this attachment comprises a cap 2 which is adapted tofit telescopically on the open end of the breather pipe. It will be noted that this cap is bent between its ends to provide a circumferential bead 3 which constitutes a stop. Moreover, the cap is provided with air intake holes Land a screen-5 is employed to cover these to prevent the entrance of particles of dust. The reference character 6 designatesa short pipe connecting memof the top of the cap her or coupling having a screw threaded end 7 for connection of the air hose .(not shown). In addition, it is provided with a reduced screw threaded end portion 8 extending through an opening in the center is threaded on this. Rotatably contacting the top of the cap and surrounding the reduced end portion of the pipe 6 is a disk 10 which is also provided with' openings 11 adapted to register with the openings 4 to:

control the entrance of air or to cut it off completely as desired. It will be noticed that this disc is confined by an outstanding flange 13 on the pipe 6 and that it is provided with upstanding lugs 13 constituting finger pieces by meansofwhich the valve may be conveniently regulated. Then too small seats 14 are formed in the webs as shown plainly in Figures 2 and 3. Finally, I employ a plurality of circumferentially and a retaining nut spaced spring clips 15 attached to the part 1' and having curved free end portions constructed to snap into one of the seats 14.

From the foregoing description and drawing it will be seen that I have evolved and produced a novel contrivance capable of replacing the ordinary breather pipe without requiring alterations in the breather pipe construction. The gist of the idea resides in the construction whereby air can besupplied as is usual through the new contriv-v ance, or the latter can be closed entirely to cut ofi' the air temporarily while an air pressure supply hoseis connected to the contrivance for forcing a current of air down-' wardly through the breather pipe to assist in draining oil from the crank case. The details and their relative arrangement and association will be plain to those skilled in the art to which the invention relates, for this reason a more lengthy description is thought unnecessary.

While the preferred embodiment of the is to be understood'that minor changes coming within the field'of invention claimed may be resorted to if desired.

vHaving thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. As a new article of manufacture, a breather pipe attachment comprising a cap adapted to fit over the open end of the breather pipe, said cap being provided with air holes, a valvefor controllingsaid holes,

2. As a new article of inanufactnre, a breather pipe attachment of. theflclassde-V scribed comprising a cap adapted to fit tele- 'scopically on the open endof a breather pipe said cap being provided in its upper end with screened openings; a rotary disc valve associated with said capand said openings, said valve being provided wlth .v pera ing lugs; and the Web p s being formed with seats, and spring clips carried by Sald .capand cooper-able with said seats for nialntainlng thevalve 1n adpisted positions: I
